Patented June 23, 1931 UNITED STATES PATENT OFFICE wiLBEa'r n. HENDERSON, or sun rrmncrsco, CALIFORNIA PARTITION-STUD CLAMP Application filed. August 22, 1928. Serial No. 301,361.

The primary object of the present invention is to provide a new and improved partition-stud clamp.

Another object of the present invention is to provide a new and improved construction for a device of the character described in United States Patent No. 1,167,899; issued to me on the 11th day of January, 1916, reference to which patent is hereby made. A further object of the present invention is to provide a more economical device of greater efiiciency than the device disclosed in the patent above referred to.

A still further object is to provide a new and improved device of the class described having a spring tension and arranged to grip instead of merely engage the inner surfaces of a pair of parallel spaced channels, and to hold said members firmly in said spaced relation.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present application wherein like characters of reference are used to designate similar parts throughout the specifications and drawings,

and in which- Fig. 1 is a broken front elevation of a pair of spaced parallel channels disclosing a pair of my clamps applied thereto;

Fig. 2 is a broken side elevation of Fig. 1 with the lower clamp shown in vertical section midway between the channels Fig. 3 is a back elevation of Fig. 1;

Fig. 4; is a transverse sectional view of a pair of channels and a clamp, disclosing the said clamp being partly applied;

Fig. 5 is a similar view showing the clamp completely applied; and

Fig. 6 is a sectional view of the clamp be- 59 fore application to the channels, disclosing the channels in dotted lines for comparative purposes.

I Referring to the drawings the numeral 1 is used to designate a pair of channels arranged in spaced parallel relation to each other and comprising the usual webs and legs to form the inner surfaces 3 and adjacent sides 4. A spring clamp member 6 comprises a central or intermediate portion 7 having a centrally located struck-up apertured lug 8 and transversely arranged indented beads 9 adjacent the'upper and lower edges of said central or intermediate portion 7 to impart rigidity to said central portion, the purpose of which will hereinafter be more fully set forth.

The intermediate portion connects two outer portions, each comprising laterally extending converging portions 11 formed by bending those portions of the clamps upon themselves to form converging spring por- 'tions arranged at a slightly less degree of convergency than that of the adjacent channel-legs which they grip and engage, said converging spring portions being also slightly longer, on their inner or adjacent surfaces, than the corresponding surfaces on the channels, by means of which arrangement said members, being shaped to engage said inner surfaces of said legs and the outer surfaces of said legs, or adjacent surfaces of said parallel channels, may firmly grip said legs when moved thereonto before the inner end of said converging members or portions 11 engage the outer edge or end of said legs, in a manner hereinafter more fully set forth.

- Formed beyond these converging portions 11 I have provided further extensions .12 which extensions 12 are formed at an angle to the central or intermediate portion 7, as disclosed in Fig. 6 of the drawings, whereby said extensions 12 will grip and press against said inner surfaces of the channels 1 with a spring tension when the clamp is applied.

In operation a suitable bolt 14 such as a nail of the proper size, and strength, is inserted through the lug 8, as disclosed in Fig. 4 of the drawings. lVhen inserting this bolt one side of the clamp will first be forced or drawn into clamping arrangement with one of the channels 1 as disclosed in the left hand side of Fig. 4: which will place said bolt or nail 14 in the position shown in said Fig. 4, in which it is shown that the resulting reaction has prevented the other portion of the clamp from moving into gripping arrangement or relation with the remaining channel 1. V I f The beveled pointl6 of the bolt or-nail 14 will now ride over the inner back corner or edge of theremaining channel, and-by-v means of a hammer or other suitable tool, the bolt 14 may be driven to slide over the back of the remaining channel .1 and thereby move the entire clamp into gripping relation with the channels 1, the intermediate portion 7 serving to hold the channels 1 rigidly in spaced parallel relation and to cause the clamp to firmly and rigidly grip, instead of merely engage, the inner surfaces and adjacent sides of said channels 1. V

, 'Itis quite obvious that by'placing these clamps at regular spaced intervals along'a pair of spaced channels that saidchannels will be firmly gripped and rigidly held in parallel spacedrelation to each other. and

thereby provide-a rigid support for a partition or similar structure.

- Having thusdescribed my invention what I claim as new and desire to secure by Letters Patent is. a J

Aclamp for partition s'tudding members comprising a spring metal strip shaped to enof each channel engaging portion being inclined relatively to each other at an angle slightly less than the angle between the inner and outer faces of the channel leg, and end portions extending laterally from the channel engaging'portions and inclined toward the plane of the body portion-to engage the inner surfaces of the back's of the channels; an outwardly disposed apertured lug struck from the body portion to receive a securin member inserted through the aperture of the lug and engaging the backs of the channels tospring the channel engaging portionsinto gripping engagement with the legs ofth'e" channels and compress the end portlons'agalnst the inner surfaces of the channel backs to exert a springgfpressure against said channels; and beads formedupon the body portion and extending laterally between the channel engaginglportions to impart rigidityito said body portion. i
